This GIS dataset is a GIS version of Alberta Geological Survey Map 139, polygon features, as mapped at 1:250,000 scale. Digitizing was originally done by Prairie Farm Rehabilitation Administration (PFRA). The data were supplied to Alberta Geological Survey (AGS) by PFRA in Arc/Info coverage format (map polygon features only). Data were subsequently checked and edited by AGS.

All available bathymetry and related information for Johnnys Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

This GIS dataset depicts the surficial geology of the NTS map area 84B Southeast (polygon features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

This dataset is a shapefile depicting the suitability of geological setting in Alberta for waste management siting. It is derived from spatial analysis of other geological input, including: bedrock topography and morphology. occurrence of major buried drift aquifers, assumed on the basis of buried channel talwegs locations. surficial geology. bedrock geology. and, drift thickness. Areas of the province are ranked Suitable, Unsuitable or Uncertain where possible. other areas are masked by lakes or have insufficient data to rank them.

The Geological Atlas of the Western Canada Sedimentary Basin was designed primarily as a reference volume documenting the subsurface geology of the Western Canada Sedimentary Basin. This GIS dataset is one of a collection of shapefiles representing part of Chapter 24 of the Atlas, Uppermost Cretaceous and Tertiary Strata of the Western Canada Sedimentary Basin, Figure 15, Lea Park/Pakowki Isopach. Shapefiles were produced from archived digital files created by the Alberta Geological Survey in the mid-1990s, and edited in 2005-06 to correct, attribute and consolidate the data into single files by feature type and by figure.

All available bathymetry and related information for Buffalo Lake were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.

The Fire Control Zone dataset is comprised of all the polygons that represent Fire Control Zones in Alberta. Fire Control Zone is legislated to show geographical areas established for the purposes of closure orders and fire control orders under the Alberta Forest and Prairie Protection Act.

This GIS dataset depicts the surficial geology of the Levellers Creek area (NTS 84E/NW) (GIS data, polygon features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the polygon features of Alberta Geological Survey Map 574, Surficial Geology of the Levellers Creek Area (NTS 84E/NW).

This GIS dataset depicts the surficial geology of the Chipewyan Lake area (NTS 84A/NW) (GIS data, polygon features). The data were created in geodatabase format and output for public distribution in shapefile format. These data comprise the polygon features of Alberta Geological Survey Map 572, Surficial Geology of the Chipewyan Lake Area (NTS 84A/NW).

Please note that this is the v1.0 version of DEP. a new version (v2.0) supercedes this dataset. The Derived Ecosite Phase (DEP) is a digital and spatial representation of ecological sites and phases in those areas of Alberta where both Alberta Vegetation Inventory (AVI) and LiDAR are available. The AVI is an imagery-based digital inventory developed to identify the type, extent and conditions of vegetation, where it exists and what changes are occurring. The most up-to-date ecological site phases can be found in the Plant Community Guides. Guides are broken into individual Natural Subregions. See the Cross Reference Section for …
